Adjusting screen brightness is a common way to conserve battery life, especially when your Windows 11 device is running on battery saver mode. However, when Battery Saver is active, Windows sometimes restricts brightness adjustments to optimize power consumption. If you want to manually set your preferred brightness level even when Battery Saver is on, this guide will walk you through the necessary steps. Before proceeding, ensure your device is running Windows 11 and that Battery Saver mode is enabled. This process involves tweaking some settings to allow brightness control during power-saving mode, providing a more comfortable viewing experience without sacrificing battery life.
What You’ll Need
- A Windows 11 device with administrative access
- Battery Saver mode enabled (optional but helpful for testing)
- Basic familiarity with Windows Settings and Control Panel
Step-by-Step
- Open the Settings app by clicking the Start menu and selecting the gear icon, or press Windows key + I on your keyboard.
- Navigate to the “System” section, then click on “Power & battery” in the sidebar.
- Scroll down to find the “Battery saver” settings. Ensure that Battery saver mode is turned on by toggling the switch to “On.”
- While still in “Power & battery,” locate the “Brightness & color” section. Here, you will see a slider to adjust the screen brightness. Try moving the slider to your preferred level. If it’s greyed out or unresponsive, proceed to the next steps.
- Open the Control Panel by typing “Control Panel” in the search bar next to the Start menu and selecting it from the results.
- In the Control Panel, go to “Hardware and Sound” > “Power Options.”
- Next, click on “Change plan settings” next to your selected power plan.
- Click on “Change advanced power settings.” A new window opens with detailed options.
- Expand the “Display” section, then expand “Enable adaptive brightness.” Set both “On battery” and “Plugged in” to “Off.” This disables adaptive brightness, which can interfere with manual adjustments during Battery Saver mode.
- Return to the “Power & battery” settings in Windows Settings. Now, try adjusting the brightness slider again. It should respond, allowing you to set your preferred level even when Battery Saver is active.
- If the slider still doesn’t work, consider disabling Battery Saver temporarily to set your preferred brightness, then re-enable it afterward.
- To disable Battery Saver temporarily, click the battery icon in the taskbar, then toggle “Battery saver” off. Adjust the brightness as desired, then turn Battery Saver back on if needed.
Common Mistakes
- Trying to adjust brightness when the slider is greyed out without disabling adaptive brightness in Power Options.
- Not turning off Battery Saver mode before attempting to set a specific brightness level, leading to restricted controls.
- Failing to save changes in Power Options, which can prevent brightness adjustments from taking effect.
- Using outdated or incompatible device drivers that may restrict brightness controls during Battery Saver mode.
- Ignoring the need to update Windows or device drivers, which can cause hardware control issues.
Tips
- Always keep your Windows 11 system updated to ensure compatibility and smooth functioning of hardware controls.
- If you frequently need to adjust brightness during Battery Saver mode, consider creating a custom power plan optimized for your needs.
- Use the quick access battery icon in the taskbar for rapid toggling of Battery Saver mode and quick brightness adjustments.
- Check your device’s display driver settings via Device Manager if brightness controls are unresponsive.
- Adjust the brightness using keyboard shortcuts (like Fn + brightness keys) as an alternative when sliders are unresponsive.
Troubleshooting
If you find that you cannot adjust brightness during Battery Saver mode despite following the above steps, try these solutions:
- Update Display Drivers: Open Device Manager, locate your display adapter, right-click, and select “Update driver.” Follow prompts to ensure you have the latest drivers installed.
- Disable Adaptive Brightness: As described earlier, disable adaptive brightness in Power Options, which often conflicts with manual brightness control.
- Check for Windows Updates: Go to Settings > Windows Update, and ensure your system is fully updated, as updates often fix hardware compatibility issues.
- Reset Power Plans: If issues persist, reset your power plans to default by opening Command Prompt as administrator and typing: powercfg -restoredefaultschemes
- Reboot Your Device: Sometimes, a simple restart can resolve temporary glitches affecting hardware controls.
- If all else fails, consult your device manufacturer’s support resources for specific guidance related to your hardware model.
